    Abstract: According to examples, a build module may include a housing, a build material chamber, and a build chamber. The build material chamber may be positioned beneath the build chamber in the housing and may include a moveable support member, in which a build material distributor is to supply successive layers of build material onto the moveable support member from the build material chamber. The build module may be removably insertable into a build receiver of an additive manufacturing system to allow the additive manufacturing system to solidify a portion of the successive layers received onto the moveable support member during the solidification process of the build material. The moveable support member may separate the build material chamber from the build chamber to block build material from the above the build material chamber from being received into the build material chamber during a solidification process of the build material.

    Abstract: In an example, a method includes forming a layer of build material and selectively applying fusing agent on to the layer based on a predetermined pattern. Energy may be applied to the layer of build material, and at least one temperature of the layer may be measured. A temperature distribution over the layer of build material may be determined, the temperature distribution indicating, for each of a plurality of locations on the layer of build material, whether fusing agent is present at that location. At least one characteristic derived from the temperature distribution may be compared to a predetermined characteristic. When the compared characteristics differ, an operational characteristic of an additive manufacturing apparatus may be adjusted.

    Abstract: In one example, an apparatus for generating a three-dimensional object includes an energy source to apply energy to a layer of build material to cause a first portion of the layer to coalesce and solidify, an agent distributor to selectively deliver a cooling agent onto a second portion of the layer, and a controller to control the energy source to apply energy to the layer to cause the first portion to coalesce and solidify in a first pattern and to control the agent distributor to selectively deliver the cooling agent onto the second portion of the layer in a second pattern independent of the first pattern.

    Abstract: In some examples, a lamp assembly for a printing system includes a heating lamp to generate heat in an active region of the printing system, and a housing comprising an inner chamber containing the heating lamp, an airflow inlet to receive a cooling airflow for provision into the inner chamber of the housing to cool the heating lamp, and a plurality of exhaust holes through which heated exhaust air is to exit from the inner chamber of the housing, the plurality of exhaust holes formed in a wall of the housing. The lamp assembly further includes an attachment element to attach the lamp assembly to a carriage of the printing system.
